Melting I²t is 1 A²s, which sets the pulse-withstand capability: a 6 A fuse with I²t of 1 clears fast on a hard short but survives inrush from a 100 µF capacitor charging through a 1 Ohm ESR. The fast-blow characteristic means it opens within milliseconds on a 200% overload — no time-delay margin for motor-start or lamp-inrush loads. ## Obsolete — sourcing reality for this 1206 fuse Littelfuse lists the 1206SFF600F/32-2 as obsolete. The 1206 (3216 metric) footprint is a standard size shared across many Littelfuse SMD fuse families, so a pin-compatible replacement from the same series or a sibling family (same package, same current/voltage rating) may exist — but no official cross-reference is published. Confirm the replacement's I²t and cold resistance against the original application's inrush and steady-state requirements before committing a new part number to the BOM.","metaTitle":"Littelfuse 1206SFF600F/32-2 6A 32V Fast Blow SMD Fuse","metaDescription":"Littelfuse 1206SFF600F/32-2 6A 32V DC fast-blow SMD fuse, 1206 package, 0.013 Ohm cold resistance.
